Product work where I am shaping the logic, the data model, the decision flow, and the longer-term system direction directly. For the broader thinking behind these pages, read the product page guide.
Passary
Offline password managerA local-first password manager built around data ownership, isolation, and zero-knowledge operation. Read the project page
The starting point here was simple: passwords should not live in a cloud vault by default. They should stay with the user, locally, encrypted.
The security model is built around Argon2id + AES-256-GCM, with a zero-knowledge approach and as small an attack surface as possible.
Right now the focus is continued product work: browser extension, mobile direction, and later self-hosted or sharing use cases.

TipSignal
Football predictions & analyticsA free football prediction site with match picks, analytics, EV-based high-odds selections, a results archive, and a bet simulator. Read the project page
The goal here was not to throw up tips and leave it there. It needed real data behind it, prediction logic, and results you can actually review.
Managing daily ingestion for 50+ leagues is also a good testing ground for concurrency, schema pressure, and query paths that need to stay predictable.
The focus is daily predictions, the analytics layer, value and EV thinking, and a transparent picture of how the picks perform over time.
The current direction includes today's predictions, high-odds picks, results archive, analytics, news, and the simulator.

Service and conversion systems
Client-facing systems.
Client-facing systems where service positioning, trust, clarity, and inbound conversion matter just as much as the build itself. For the broader version behind that work, read the local service site guide.
DJ Canis
Business logic & service positioningA conversion-focused site for a Swiss wedding and event DJ, built to present services clearly, build trust fast, and drive booking inquiries. Read the case study
This one is different from Passary or TipSignal. It is client-facing web work: service positioning, clear landing structure, stronger trust signals, and a site that needs to help convert real inquiries.
The public site leans on wedding DJ, event DJ, and Switzerland-wide service positioning, with reviews, equipment details, mixes, gallery sections, and direct booking prompts.
The work here was about making the offer easier to understand, giving the site more presence, and turning it into something that supports the business instead of just existing online.

Szabó Gabriella Eszter
Business logic & service positioningA personal teaching and musician site built around trust, biography, lesson positioning, and direct local contact. Read the case study
This is another service-driven site, but with a completely different tone from DJ Canis. It needed to feel personal, credible, and more refined, while still making the offer easy to understand.
The live site centers on piano teaching in Pecs, biography, multilingual teaching, testimonials, and direct contact paths, with a much more personal and editorial presentation.
The work here was about shaping a stronger online presence for an individual professional, where credibility, atmosphere, and clarity matter as much as the structure itself.
